Where To Get Misc Parts...

I need some random parts for my 2003 stang. If anyone knows a place to get them or has some to sell let me know! Here's what I'm looking for...
1. Clips for the headliner...two of them that hold it up where it meets the back window
2. I don't know what to call it... the large piece just above the back seats. If you fold down the seats you can see the 3 bolts that hold it in. The brackets that hold mine in are broke. I doubt there's a way to fix it besides replacement.
3. Rubber molding where the back window meets the trunk

I have been thinking of going to the junkyard. I'm sure there's a few stangs there. I want to get a few of the clips so i have some JIC. I'd like to get new parts, but they would be expensive. I think I'm going to the ol junkyard then. I was hoping some people on there would have spares lying around. At least the clips. Just gimme a heads up if you find any!
